The HSS 4–32 mm spiral stepped cone drill bit is the essential tool for drilling several diameters with a single bit. Made from high-quality HSS high-speed steel, this drill bit is designed to deliver smooth cutting, optimal heat dissipation and far greater longevity than conventional drill bits.
Thanks to its spiral flute and dual clearance angle, it guarantees precise drilling with minimal heat build-up, whether in steel, plastic, aluminium or other materials.
